So we are tentatively planning a short plane trip with WestJet next month...flight would be about an hour and a half direct. I am going to take my dog who is a schnoodle and because of his height would be too big to take in cabin. I am nervous about him flying underneath in cargo as I am worried he will be really stressed.

Any words of wisdom, experiences, etc.? I am imagining all these worse case scenarios in my head of things that could happen.
